I've only had one issue with ONE camera (Fujifilm S2 Pro) and that includes owning between 1973 and today:
Minolta SR-T101 (my sister still owns it)
Minolta X-E7 ( I still own it and it still works)
Digital: Fuji 4900z 4.3 megapixel - outstanding camera
Nikon 8700 8mp - never had an issue through sale
Nikon 300 6mp - never had an issue through sale
Nikon D700 12mp - Still use it and still works perfectly with over 200,000 images
RB67 Pro Medium Format
2 ea Mamiya 645 AFD Medium Format
2 ea Yashicamat Twin Lens reflex
Fujifilm S1 Pro - ONE of the BEST early digital cameras with gorgeous colors and a Base ISO of 320, 3.2mp
Fujifilm S2 Pro. The S2 Pro developed a bad sensor and Fuji in Edison replaced the sensor, and shutter free of charge with a. two day turnaround after I dropped it off.
X-E1 - never had an issue
X-T1 still own it. Rubber grip started to come loose and I used gorilla glue to fix it
X-T2 Camera took a salt water bath and self-destructed. Not worth repairing per Fuji's repair estimate, sold for parts
X-H1 - Still shoot with it never had an issue
G50R and 100S. -- Haven't had an issue. Fingers crossed I don't
